Question 6 Option 1
Two cars leave an intersection at the same time, each on a different straight road. The angle
between the roads is 12º. One car travels 90km/h and the other travels at 120 km/h. After 20
minutes, a police helicopter hovering 1.0 km above a line on the ground connecting the two
cars, notes the angle of depression to the slower car is 14°. What is the horizontal distance (i.e.,
distance along the ground) from the helicopter to the faster car? Answer to the nearest
kilometre. Excuse the poor drawing :)
